Design outcomes

Primary

MeasureTime frame
Current primary outcome measures as of 23/08/2023: Implementability of the Kort intervention: School health nurses will report on the perceived implementability (acceptability, feasibility, appropriateness, usability) of the KORT intervention using the Acceptability of Intervention Measure (AIM), Intervention Appropriateness Measure (IAM), the Feasibility of Intervention Measure (FIM), and the Intervention usability scale pre- and post-intervention and follow up (T1, T3, T4). Intervention fidelity: 1. School health nurses will complete a brief dynamic questionnaire about intervention fidelity after each consultation with adolescents, following a “flexibility for function” conceptualization of intervention fidelity 2. Audio recordings of each consultation with school health nurses and the adolescents, analyzed using a newly developed fidelity coding framework Effects on proximal outcomes for adolescents’ emotion regulation using experience sampling: 1. Daily experience with emotion regulation strategies will be measured using a daily diary, given every evening during the data collection period 2. Momentary affect and emotion regulation strategies will be measured using momentary ecological assessment (EMA) of affect and regulation. We will ask half of the sample (n = 20) only to answer the daily diary, and the other half (n = 20) will be asked to also report on momentary affect and emotion regulation strategies three times a day for a week over two months (experience sampling period). Effectiveness of the intervention: 1. Adolescents self-reported emotion regulation and mental health measured using Difficulties in Emotion Regulation Scale short form (DERS-SF) at T1, T2, T3, T4 Adolescents' and health nurses' experiences with Kort and its value: 1. The adolescent's experiences of Kort and its value will be studied in a follow-up interview 2. The school health nurses' experiences with Kort, its implementation, and its value, will be studied in follow-up focus group

Secondary

MeasureTime frame
Current secondary outcome measures as of 23/08/2023: 1. Mental health measured using the Behavior and Feelings survey (BFS) at T1, T2, T3, T4 2. Well-being measured using the Short Warwick-Edinburg Mental Well-Being Scale (SWEMWBS) at T1, T2 and T3, T4 3. Mindfulness measured using three subscales of the Five-Factor Mindfulness Questionnaire (FFMQ-15; Describing, Non-reactivity, & Non-judging) at T1, T3, and T4 4. Cognitive fusion measured using the Cognitive Fusion Questionnaire (CFQ) at T1, T3, and T4 5. Self-compassion measured using two subscales of the Self-Compassion Scale for Youth (SCS-Y; Self-kindness & Self-judging) at T1, T3, and T4 6. Loneliness measured using the Three Item Loneliness Scale (T-ILS) at T1, T2 and T3 7. Friendship measured using the subscale of Peers and Social Support from the KIDSCREEN-27 at T1, T3, and T4 8. Mental Health Literacy measured using seven items created for this study, asking the adolescents whether they agree with statements about what is important for mental health, the scale is present at T1, T3, and T4. 9. Functional Impairment measured using two items created for this study asking to what extent mental health symptoms impact adolescents’ daily lives, the items are asked at T1, T3, and T4 10. Sleep and screen time use measured using items developed for the study at T1, T3, and T4 11. Measure of Innovation Specific Implementation intentions (MISI) at T1, T3, and T4 Timepoints: T1 = Before baseline experience sampling Experience sampling baseline = 2 weeks after T1 Experience sampling period (intervention) = From first intervention consultation, lasting 11 weeks T2 = Post intervention (intervention length is not fixed, so T2 can be anytime between three weeks to five months, but health nurses are prompted to stay within 11 weeks when feasible) T3 = 11 weeks after the experience sampling period started T4 = 11 weeks after the experience sampling period ended (follow-up) Previous secondary outcome measures: 1. Mental heal
